Auto transformer symbol

The auto (Greek for self) prefix refers to the single coil acting alone and not to any kind of automatic mechanism. In an autotransformer , portions of the same winding act as both the primary and secondary sides of the transformer. The electrical transformer is a component consisting of two or more coils coupled by magnetic induction. The autotransformer has only one winding.

In a step-up autotransformer , the secondary is the longer winding, and the primary. DXF, DWG and Visio formats available.

Non short-circuit-proof autotransformer. Short-circuit- proof autotransformer. Reactor without overload protection. This symbol is part of collection(s). Safety isolating transformer.

Phase auto transformer symbol. High reactance autotransformer ballast This ballast is an autotransformer , which means that it has two windings connected electrically, and coupled magnetically. The high reactance autotransformer ballast can boost line voltage to any starting voltage required by the .

Notes: (1) To indicate a fail-safe function, the letter F may be used adjacent of the graphical symbol. To identify the variable auto - transformer of the type short-circuit proof, the symbol. Then an autotransformer can be used. This has a single, tapped winding. Its schematic symbol is shown in Fig.

A for an air core, and Fig. B for a ferromagnetic core. An autotransformer can be either . Melting opens Transformer with taps FIGURE 6. Transformer with iron core the electrical path, stopping the flow of electricity.

To restore the flow of electricity, the fuse must be replaced. Autotransformer FIGURE 6. An air-core transformer symbol is shown with out vertical lines between the windings. A transformer with only one winding. The common point may also be located .
